CONTENTS:
The Canon of the Moslem physician and philosopher Avicenna is an encyclopedia of medicine and was used by physicians until after the Renaissance. It was translated into Hebrew by Nathan ha-Meati in Rome in 1279. Cf. M. Steinschneider, Die hebrischen bersetzungen des Mittelalters und die Juden als Dolmetscher (Berlin 1893) p. 683.

On fols. 118r-131v of the present manuscript there is a copy (the end missing) of Ma'amar ha-Nikhbad, Moses ben Maimon's medical treatise on poisons, translated by Moses ibn Tibbon. Cf. M. Steinschneider, ibidem, p. 764.

Both works have been published and are well represented in other manuscripts.
